Twice in 2019 I had to loan a bass to someone for their gig. One was a charity gig, young band going on early and had never played through a PA, you couldn’t hear the bass over the buzz it was making, so loaned him mine.
Second time was a band setting up in my local, guy sound checked, but couldn’t get a peep out of the bass when they were due to start. I’d had a couple of pints, but only lived two minutes away, so said if someone gave me a lift home, he could have something to get him through the gig. Good deed done and guy was eternally grateful, ( and I drank free all night ).
